Along with feedback you have already received - I also think you might want to take a closer look at the perspective. Especially of the girl/mat on the floor.

When you look at the lines of the furniture piece on the back wall with the tea pot on it and compare it to the line of the mat - it makes it feel to me like the mat is going uphill - but they are both supposed to look like they are on the same floor surface.

Look here at the two lines and I think you will see what I am saying.

So I did some adjusting and I think if you get those to line up in a way that it looks like they are both on the same floor plane it really helps.
Also those two yoga blocks - along with the perspective being a little wonky - they also seemed way to large in relationship to the girl. So I reduced their size and tried to fix the perspective lines a bit and I think it also will help the piece read better.

Very nice idea, a fun image! As @Rich-Green pointed out there seem to be some issues with perspective throughout the image. I have tried to overlay a grid as good as I could (I fit it to the bottom of the shelf cabinet.

As you can see if you check the grid, the top of the cabinet does not fit to the same horizon, and the side of the cabinet does not use the same vanishing point as the.poster and the window (to which I fit the left vanishing point) The shelfs on the wall are also not using the same vanishing points (and maybe not the same horizon), as well as the shelf where the candles are. The mat on the floor is the most evident mis-match. In general you do not need to draw everything to the same vanishing points (things look very stiff if you do that), but there can be only one horizon (excluding inclined planes, but I am getting too technical), and of course if things align to a wall they have to have the same vanishing points. You could rotate the mat so that it is not parallel to the wall, but the new set of vanishing points need to relate to the others.

Sorry, I always tangle myself up in this - perspective is one of my pet-peeves.
Hope to see this in color!

@smceccarelli arrrrrrgh I know! Perspective is my arch nemesis, which is why I tend to always draw characters floating on white empty backgrounds. For this project, I really made myself try and draw a space, but I wasn't formally trained on perspective so I "eyeball" it and screw it up :(

I'm already tinkering with some changes in photoshop to get it closer. Is there a place online to find these grids to use? Or did you add it with photoshop? Thanks so much for taking the time to help me sort it out. I'll get the line work as tight as I can and then tackle color!

@kimchizerbe unfortunately you need to draw the grid yourself in Photoshop. Other software (ProCreate, Illustrator and ClipStudioPaint) have semi-automated grids, but you still need to know how to set them up.
I know perspective can seem like a hard nut to crack, but I believe it is worth studying it. I actually love it, but I admit I am probably skewed by my first life in science ;-)

So I took the 50 items crit class with Will Terry and I finished my Hippie Cat Lady! I hope you guys like it. I had SUCH a blast working on this piece, and learning new techniques. Thanks to @Will-Terry and all the other awesome students in this class. So much fun. !
